Dynamic Parameters Estimation Based on Set Inversion and Interval Analysis Algorithm

摘要：

　　In the paper,an approach,based on bounded-error estimation via interval analysis,is presented to identify viscous damping coefficient and Coulomb friction coefficient of such-rod pumping system of directional well.The approach assumes the error of colleted output data of suck-rod pumping system is bounded.Hence,the problem of parameter estimation can be viewed as that of set inversion,which will be effectively solved via interval analysis.The main advantage of the proposed method in comparison with the traditional estimation methods is that,as it is global,it bypasses the problem of initialization.Moreover,the method avoids amount error due to transformation of measurement output data.An identification example is given to show the correctness and efficiency of the proposed method.
